@TRS-80 said in Finally, progress! (evidence based radio testing method):

Perhaps one of you professional angry pixie wranglers out there can verify that there is in fact something to the "two capacitors of different values in parallel" theory?

Two capacitors in parallel lowers the ISR of the capacitance attached to the circuit, meaning it "reacts faster" to the changes in voltage and acts as a better filter. As BearWithBeard said, you can achieve a similar effect by combining electrolytic and ceramic capacitors. If you have a lot of LF and HF noise, that might give you a better result.

Ah, I think cussing is warranted here, I copied the radio configuration from my old sketch to the new ones, the node had:

#define RF24_DATARATE RF24_2MBPS

The GW has:

#define MY_RF24_DATARATE RF24_2MBPS

Lesson learned: Never copy configuration from an existing older sketch, you never know what has been deprecated without a warning. MY_RADIO_NRF24 threw a warning and I fixed that, had no idea about RF24_DATARATE and I didn't notice it. :sweat_smile:

@NeverDie I personally took a bottle of nail polish and coated every sensor I had. I had a hunch that moisture seeping might affect the capacitive sensors so I took precautions. They've lasted a year now with no sign of deteriorating.

Small update to the situation. With awesome work done by @jkandasa, the main developer of MyController the InfluxDB backend is now fast enough to almost keep up with the data inserted, that's a big improvement. This means the last issue I had with MyController just got resolved :D and it's suitable for my use-case. Yay!

There's this nice HAT for the Raspberry Pi you might find interesting :) : https://gitlab.com/electronutlabs-public/indrium-pi-hat

On another topic, I would honestly like to see MySensors using OpenThread or BLE Mesh transport...

@cYnd I know, but the lack of proper solder flow (on at least two pins) and a cold joint should not happen even if soldered from the other side. I'd fix it just to be sure it doesn't cause any erratic issues.
